The Sram PC-971 chain is an upgraded version of the venerable (and now discontinued) PC-970. SRAM made some minor tweaks to the PC-971 to further enhance shifting performance with Truvativ chainrings while continuing to offer fast and accurate shifting in SRAM or Shimano drivetrains.

I'm a Commuter that puts in @2k back and forth to work, as well as ride in hill-climbing challenge's and charity rides throughout the year. Had a chain like this last season and loved it. Just need to keep it clean and lubed, and it will get you over 3000 miles.

SRAM chains always use the PowerLink chain connector. They work perfectly with Shimano gears. I recommend buying the Park Tool master link pliers and a stiff hook wire to hold your chain together while you connect it to your bike. You need a chain-breaker tool to shorten the chain if you don't have a wide range of gears. Buy a new chain every 1000 - 2000 miles to keep your expensive chain rings and rear cluster from wearing out prematurely.

I have just gotten back into cycling late last year and am restocking my tool box with the things I need such as spare tubes, inflation systems etc. for out on the road for just in case of a breakdown. I have always used shimano, but I got the SRAM at a great price,it was easy to install (thanks to the combo tool, also from Nashbar) and it shifts perfect and I am very happy with it.

I needed to replace a Shimano Chain that had a few thousand miles on it and decided to try this Sram. I have only used Shimano in the past and have been satisfied. The only downside to the Shimano chains is their link system which requires a chain breaker and new pin each disassembly.

The Sram was easy to install using the master link. You still need a chain breaker to do the initial sizing. I plan on taking the chain off the bike to clean it using the quick link instead of cleaning it while still in the bike.

I have put a few hundred miles on the chain with no problems. I can not attest to durability yet. I also replaced a 105 cassette with a Sram 970. Shfts are just as smooth and quiet.
